[PATCH] D108837: [SimplifyCFG] Ignore free instructions when computing cost for folding branch to common dest

I've been meaning to do something along those lines.

This probably should probably be TTI-cost driven completely, not simply instruction count, but the cost model here is dubious even ignoring that.
